What is the Land Treatment Digital Library (LTDL)

The LTDL is a centralized digital library hosted by the USGS for federal managers and scientists. The LTDL stores and displays data from previously established land treatments or what often are called legacy data. Data come from project plans and implementation reports, monitoring reports, spatial data files from geographic information systems, digitized paper maps, and digital images of land treatments. Once compiled, legacy land treatment data can be used by federal managers and scientists for compiling information for data-calls, producing maps, generating reports, and conducting analyses at varying spatial and temporal scales. Read the LTDL factsheet  for more information about the background of the project and key features.

A Brief History

The LTDL was originally developed by the U.S. Geological Survey’s Great Basin Integrated Landscape Monitoring Pilot Program in 2007. The LTDL archives grew with contributions from the Joint Fire Science Program from 2008-2009. On 17 September 2009, the U.S. Geological Survey (USGS) and Bureau of Land Management (BLM) signed a memorandum of understanding (MOU) to catalog land treatments in the western U.S. into a centralized digital library hosted by the USGS for federal and state land managers and scientists.
